Tell us what’s happening:

how the hell am i not following the instructions above ive done it ive done the inheritance bs no? l

Your code so far

class R2Vector:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        
    def norm(self):
        return (self.x**2 + self.y**2)**0.5
        
    def __str__(self):
        return f'{self.x, self.y}'

# User Editable Region

class R3Vector(R2Vector):
    pass
R3Vector().norm().__str__()

# User Editable Region

v1 = R2Vector(2, 3)
print(v1.norm())
print(v1)

No, you have not done this ‘bs’ quite correctly

You need to follow the instructions exactly. Don’t add anything extra that’s not specifically mentioned in the instructions or hints.

Hi @Mr.Merati

From the example:

class Oak(Tree):
    pass

There should not be any code added after the pass keyword.

Happy coding
